- Verify that the lines \(\left. \mathbf { r } = \begin{array} { r } - 5
3
4 \end{array} \right) + \lambda \left( \begin{array} { r } 3
0
- 1 \end{array} \right)\) and \(\left. \left. \mathbf { r } = \begin{array} { r } - 1
4
2 \end{array} \right) + \mu - \begin{array} { r } 2
- 1
0 \end{array} \right)\) meet at the point ( \(1,3,2\) ). - Find the acute angle between the lines.
